Welcome to the Q&A Forum

Moz's index isn't a complete view of the web, but we try to crawl quality sites out there. Our index is always growing. But to be frank, no one -- not even Google -- crawls the entire web. There are just too many pages out there and computing power is expensive. Google crawls the most links simply because Google is a bigger company with more money and more servers and more engineers and who's business depends on serving web pages to everyone. At Moz, we focus on quality sites because we believe (and hope) our customers and community are focusing on high quality links that are still active, which are going to give them the best SEO results. (Also a huge part of the web is just spam nonsense.) Many SEOs -- and I include myself here -- will use multiple sources of link indexing for the broadest view of the web and their sites. I use Moz's OSE and Google Webmaster Tools (free and big, but includes lots of spam, which can be great if you're fighting a Penguin penalty). Others will use OSE, GWT, and OSE competitors like Majestic and Ahrefs, especially if link building is huge for them and they want to account for every penny. Every index is a bit different.

Hi Kristian, Without looking at your analytics, it's a little difficult to say for sure, but there are a few things for you to consider. First, content isn't king unless it is related to the subject and doesn't just waffle about a product. A page that is well structured and allows people to fulfill a function quickly and easily, is likely to trump one that makes the visitor experience a miserable one. Yes, create amazing and unique content, but you don't need to go overboard in all cases. Secondly, are any of your pages similar to each other? Are you at risk of some pages competing with others in Google? If so, then you might be falling foul of duplication / keyword cannibalisation issues. In these cases, make sure that you have pages setup with rel=canonical correctly. This is very common with e-commerce sites. Finally, do a bit of a page sanity check. Are the keywords that are underperfoming doing so because you aren't using the correct group of related words and phrases that Google would expect to see on those pages? This is one of the more common issues that sites fall foul of and with a little research, one of the easiest to correct. I hope this helps -Andy
